Air strikes on rebel-held areas of Aleppo killed 200 civilians including 18 children during the past seven days of intensified violence in the northern Syrian city, the Syrian Observatory for Human Rights has said.
70 civilians, including 13 children, were killed by rebel shelling into government-held areas of the city during the same period, the British-based monitoring group said.
Eight more civilians, including three children, were killed by government shelling into areas not under its control in the city, the Observatory said.
The death toll from a hospital hit by air strikes in Aleppo rose to at least 50, including six medics, according to Médecins Sans Frontiéres.
The hospital, in a rebel-held part of the divided city, was struck overnight Wednesday-Thursday in an attack that was widely condemned abroad.
Meanwhile, US funding has been suspended for aspects of the Syrian aid programme operated by Irish charity GOAL due to "alleged supply chain irregularities."
